レーザー技術: 虹の彼方
Laser technology: Over the rainbow p459
Many laser diodes provide light in only a limited range of the visible spectrum. A hybrid laser made out of plastic, driven by a high-power light-emitting diode, looks to offer a more flexible approach.

細胞生物学: 分解を行う2本の手
Cell biology: Two hands for degradation p460
Living cells must do away with regulatory proteins that are not needed. News comes of a considerable advance in understanding how the main agent of destruction, the proteasome, catches its targets.

生物物理: 細胞が這い回り用の形態をとる仕組み
Biophysics: Cells get in shape for a crawl p461
A cell's shape changes as it moves along a surface. The forward-thinking cytoskeletal elements are all for progress, but the conservative cell membrane keeps them under control by physically opposing their movement.

天文学: いきなり登場した超新星
Astronomy: Supernova bursts onto the scene p462
The stellar explosions known as supernovae are spectacular but common cosmic events. A satellite telescope's chance observation of a burst of X-ray light might be the first record of a supernova's earliest minutes.

In recombinational DNA repair, nearly identical sequences in chromosomes are found and swapped. Structures of the RecA–DNA complexes involved provide insight into the mechanism and energetics of this universal process.
